MP/H Rules--Lung: Why the term "nodule" is not included as an equivalent term along with tumor, mass, lesion and neoplasm in the 2007 lung multiple primary rules?
Answer revised July 2008
For cases diagnosed 2007 or later:
For the purpose of applying the Lung MP/H rules, the word "Nodule" can be used interchageably with "Tumor," "Mass," "Lesion" and "Neoplasm." HOWEVER, this does NOT apply to casefinding or staging.
This revision will be added to the next version of the MP/H rules. Sinq question 20071028 will be revised.
Radiation Therapy--Prostate: Is the regional treatment modality XRT best coded to 50 (brachytherapy, NOS), 53 (LDR) or 54 (HDR) when the documentation indicates only "I-125 seeds" to the prostate?
Assign code 53 [Brachytherapy, interstitial, LDR] for seeds to the prostate. Seeds are always low dose because they are left in place and the radioactivity decays over time.
MP/H Rules/Recurrence--Breast: Do we use a pathologists comment of "recurrent ductal carcinoma" found in the pathology report for a new specimen to determine whether the new specimen actually represents a new primary or recurrent disease? See Discussion.
The patient had a left breast cancer LIQ, ductal with DCIS. Nodes (-) diagnosed in 1998
Treatment: Lumpectomy-clear margins
Refused radiation
Hormone therapy: Tamoxifen
Present: June 2007
Left breast-invasive ductal ca, UOQ
Pathology report comments: Recurrent ductal ca.
Left axillary nodes (+)
For cases diagnosed 2007 or later, apply the 2007 MP/H breast rules. Go to the multiple tumors module and begin with rule M4. Stop at rule M5: tumors diagnosed more than 5 years apart are multiple primaries.
The only time you can accept a pathologist's statement of recurrence is when the statement is made based on a review of the slides from the previous diagnosis compared to the slides from the current diagnosis.
MP/H Rules--Urinary: How many primaries are abstracted when a patient has a May 2000 invasive papillary transitional cell carcinoma of the bladder, a November 2004 invasive papillary transitional cell carcinoma of the right ureter and a May 2007 urothelial carcinoma in situ of both the left and right ureters?
For cases diagnosed 2007 or later:
Using the pre-2007 multiple primary rules, the PTCC of the bladder in 2000 and the invasive TCC of the right ureter in Nov. 2004 would have been abstracted as separate primaries.
Use the 2007 MP/H rules to evaluate the May 2007 diagnosis. Start with rule M3. Stop at rule M8. The May 2007 diagnosis is the same primary.
Rule M4 does not apply because of the 2000 bladder primary. A clarification will be added to M4 to stress that for the urinary rules, any urinary tumor up to the present point in time is counted when applying this rule.
MP/H Rules/Multiple Primaries/Laterality--Brain and CNS: How many primaries are to be abstracted and how is laterality to be coded for two meningiomas, one occurring at the midline and the other in the right termporal region? See Discussion.
MRI of the brain shows two meningiomas: One is stated to be 'midline' (laterality code 9) and one is stated to be in the 'right' temporal region. The rules state if same site (C700), same histology & laterality is same side or one side unknown, then abstract as single primary. Based on this, the MRI findings would be one primary, but how should laterality be coded?
For cases diagnosed 2007 or later, abstract two primaries. The lateralities of both meningiomas are known. Right (code 1) and midline (code 9) are different lateralities.
Ambiguous Terminology/Date of Conclusive Terminology: If there is an unknown date of diagnosis, should the Ambiguous Terminology field always be coded to 9 and the Date of Conclusive Terminology be coded to 99999999? See Discussion.
Scenario: Mammogram is suspicious for carcinoma, unknown date in 2007. A biopsy prior to admission to reporting facility is positive for carcinoma. Patient seen at reporting facility in June 2007 for treatment.
The purpose of the data item "Ambiguous Terminology" is to flag cases entered into the registry based on a diagnosis with ambiguous terminology. Because the case above was entered into the registry based on conclusive terminology, code Ambiguous Terminology to 0 [Conclusive term] and code Date of Conclusive Terminology to 88888888 [not applicable].
MP/H Rules/Multiplicity Counter--Lung: If metastatic tumors are not counted in this field, should the multiplicity counter be coded to 01 for a case with a primary left lower lobe of lung tumor with a satellite tumor in the left upper lobe?
For cases diagnosed 2007-2013:
No, code multiplicity counter to 02 [two tumors present]. According to the multiple primary rules, these two lung tumors are reported as a single primary. Record the number of tumors reported as a single primary in Multiplicity Counter.
Multiplicity Counter no longer required by SEER as of 1/1/2013.
Cell indicator--Lymphoma: If the primary site for a lymphoma is stated to be the lymph nodes but there is no biopsy of a lymph node, can the immunophenotype designation for a lymphoma be coded based on a bone marrow or liver biopsy indicating "diffuse large B-cell lymphoma"?
For cases diagnosed prior to 1/1/2010:
The cell indicator or immunophenotype designation for lymphomas may be coded from pathology reports on tissue from bone marrow or liver when there is no tissue from the primary site. Code information on cell type from any available source.
See the Appendix C of the 2007 SEER manual, Coding Guidelines for Lymphomas, pages C-1055 to C-1056 for more information about coding this field for lymphomas.
For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
Reportability/Histology: Is a case reportable if the Final Diagnosis in a pathology report indicates a non reportable diagnosis but the Diagnosis Comment on the same report indicates a non reportable diagnosis followed by a reportable diagnosis in parenthesis? See Discussion.
08/13/2007 polypectomy final diagnosis: tubulovillous adenoma with severe epithelial atypia. Dx Comment (on same path) ...atypia including focal cribriform glandular architecture (carcinoma in situ).
This case is reportable as carcinoma in situ. The histology code is 8263/2 [adenocarcinoma in situ in a tubulovillous adenoma].
According to our pathologist consultant, a "comment" in a path report is a part of the diagnosis - it often elaborates on or clarifies the diagnosis. Placing [carcinoma in situ] in the comment, even in parentheses, indicates that is the appropriate diagnosis for our purposes.
CS Tumor Size--Melanoma: How is this field coded when a smaller invasive and a larger in situ melanoma are reported as a single primary? See Discussion.
Patient has a 1.2 cm lesion right upper arm with a diagnosis of melanoma in situ. A second lesion on right wrist, 0.5 cm mole, has a diagnosis malignant melanoma, Breslow's 0.78, Clark's level III.
According to the 2007 MP/H rules, this is a single primary. Because the larger lesion is completely in situ, do you ignore it altogether and go with the smaller, invasive lesion? SEER Program Manual 2007, page 127, rule 4.l, states that when two lesions are reported as a single primary, code the size of the larger lesion, which in this case would be the in situ.
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Code CS Tumor Size as 005 (0.5 cm). Code CS Tumor Size based on the invasive lesion.
Use the data items "Multiplicity Counter" and "Type of Multiple Tumors Reported as One Primary" to document that there are two tumors present, in situ and invasive.
